Dietary supplements face scrutiny over longevity claims and cognitive risks

Recent research has raised concerns regarding the efficacy and safety of common dietary supplements used for healthy aging. A dietitian from the Medical University of Graz notes that commercial longevity products and specialized supplements often lack strong scientific evidence. Experts suggest that long-term dietary patterns, specifically those centered on minimally processed, plant-based foods and high fiber intake, are more effective for extending disease-free years than isolated superfoods or expensive infusions.

Furthermore, a study from the University of Florida suggests that glucosamine, a widely used supplement for joint pain, may be linked to increased risks of cognitive decline. The research indicates that glucosamine could potentially increase the mortality risk for individuals with Alzheimer's and related diseases by 25 percent. The study posits that glucosamine may cross the blood-brain barrier and influence metabolic pathways that contribute to cellular dysfunction in Alzheimer's patients.

Additionally, studies are examining whether common supplements like Vitamin D and Omega-3 might act differently in aging bodies due to changes in metabolism and organ function. Research from the University of California, San Diego also highlighted that anticholinergic medications may increase the risk of cognitive impairment by reducing acetylcholine activity.
